The Sonoff Mini R4 Extreme is an ultra-compact WiFi smart switch that turns traditional switches into automated hubs. It fits easily into tiny mounting boxes, features an innovative "Detach Relay" mode, and supports external switches or eWeLink-Remote control. Fully NRCS and ICASA approved for South African installations.
Description
Extreme Compactness & Versatile Control
Thanks to its break-through mini sizing, the MINIR4 fits effortlessly into various mounting boxes, including the smallest EU-type, 86-type, and 120-type boxes. It is highly adaptable, supporting multiple external switch setups such as momentary switches, door exit switches, SPDT switches, latching switches, and even dry contact sensors.
Advanced Detach Relay Mode
One of the standout features of the MINIR4 is its "Detach Relay" mode. When activated, it separates the state of the physical external switch from the internal relay. This means turning off the physical wall switch won't take your smart bulbs offline—allowing you to always maintain seamless app control and automation schedules.
eWeLink-Remote Gateway Function Feature
The MINIR4 doubles as a local gateway for "eWeLink-Remote". You can easily pair it with wireless sub-devices like the Sonoff R5 or S-MATE. This lets you control the MINIR4 locally and reliably without an internet connection, or use the switch to trigger other smart scenes in your ecosystem.
Safe, Reliable, and Certified
Safety is a priority. The Sonoff MINIR4 features TÜV, CE, and FCC certifications. For complete peace of mind in South Africa, it is fully NRCS and ICASA approved.
Key Features
Super Tiny Size: Ultra-compact footprint allows installation inside the smallest European and standard mounting boxes.
External Switch Control: Seamlessly connects to momentary, latching, SPDT, door exit switches, and dry contact sensors.
Detach Relay Mode: Separates switch mechanics from the relay so physical switching doesn't cut smart bulb power.
eWeLink-Remote Gateway: Pair with Sonoff R5 or S-MATE for local wireless remote control signals.
Certified Compliance: Backed by TÜV, CE, and FCC standards, as well as local NRCS & ICASA approvals.

Will the Sonoff MINIR4 fit inside my existing wall switch box? +
Yes! The MINIR4 features an exceptionally tiny design (39.5x33x16.8mm) specifically engineered to fit into tight spaces, including small EU-type, 86-type, and 120-type wall boxes.
-
What is "Detach Relay" mode and why do I need it? +
Detach Relay mode isolates the physical wall switch from the internal electrical relay. If you use smart bulbs, this feature ensures that flicking the wall switch won't turn off power to the bulb, allowing it to stay connected to your app and automation routines at all times.
-
Can I use this device legally and safely in South Africa? +
Absolutely. The Sonoff Mini R4 Extreme is officially ICASA approved and registered with the NRCS (Registration number: 1942XX/001), ensuring it meets all local regulatory safety standards.
-
Does it require a hub to connect to my phone? +
No. The MINIR4 connects directly to your home's 2.4GHz WiFi network, letting you manage your devices natively through the eWeLink smartphone app.
